Change a screen's settings on the screen itself (0.2.52)

Holding the top bar for about a second and a half opens a settings page on the
screen, with a blue line filling along the top edge while you hold. A built-in
screen.settings tile and the esphome.<screen>_open_settings action open it too.

The page is one constexpr table of rows in settings_screen.h: Brightness,
Night, Screen (clock, back to page 1, swiping, rotation) and This screen (name,
address, firmware, Home Assistant, Restart). Toggles flip on a tap, numbers and
times step with -/+ (a held time walks whole hours), a choice cycles in a chip,
and a row that depends on a switch above it is greyed out. The LVGL objects exist
only while the page is open: +608 bytes of RAM and +10.7 KB of flash on the CYD.
A change is saved, applied and reported through the existing screen_setting
event, so ESP Screens shows the same value within a second.

New setting auto_home (default on, 2 minutes): an open card, the settings page
or a later page goes back to page 1 after that long without a touch, not only on
standby. It travels beside the frozen eleven-key settings block with its own
preference, so older firmware and older apps keep working.

docs/SETTINGS.md is the recipe for adding a setting; the Claude skill explains
the page. Firmware 0.2.44.
